I used the DSLpanel from the desktop and clicked on the Backup/Restore icon. Afterwards I put in the dedicated device (in my case sda1). The backup.tar.gz file was written! Then I copied the file backup.tar.gz in the same folder on hda1 like minirt24.gz is.Then I changed the dedicated call (initrd) up in the lilo.conf from minirt24.gz to backup.tar.gz. After reboot NO DSL X Setup comes up any more.
